LoRa Gateway Router Product Description
The LoRa gateway router is an industrial-grade IoT device integrating a private LoRa protocol with dual-link 4G/3G/2G connectivity. Its core function is to convert LoRa terminal data into 4G / wired / WiFi uplink for cloud transmission. It is designed for long-distance, low-power, and harsh-environment IoT data acquisition and transmission.
The product adopts a high-performance industrial-grade 32-bit communication processor and industrial wireless modules. It runs on an embedded real-time operating system and provides:
- 1× RS232 (optional RS485/RS422)
- 1× Ethernet LAN
- 1× Ethernet WAN/LAN combo port
- 1× WiFi interface
It can simultaneously connect serial devices, Ethernet devices, and WiFi devices, enabling transparent data transmission and routing functions.
This product has been widely used in M2M industries across the IoT value chain, including smart grid, intelligent transportation, industrial automation, smart buildings, fire protection, public safety, environmental protection, meteorology, digital healthcare, remote sensing, military, aerospace, agriculture, forestry, water management, mining, and petrochemical sectors.
